Ch 3 biology Flashcards
the part of the plant that produces seeds for reproduction
flower
concets the flower to the stem
pedicil
holds the developing seeds
receptacle
the most conspicous part of the flower
petals
little green leaves under the petals
sepals
organs that produce pollen
stamen
contains sperm cell of the male plant
pollen
central structure of the flower
pistil
a type of stamen that produces pollen
anther
base of the pistil
ovary
female reproductive cells in the ovary
ovule
female reproductive cells
eggg cells
connects ovary to the tip of the pistil
style
receives pollen for the plants flower
stigma
flower containing all 4 basic flower components
complete flower
flower that doesn’t contain all 4 main parts of the flower
incomplete flower
4 basic parts of the flower
1.sepals
2.petals
3.stamens
4.pistill
flowers that only bear stamens
staminate
flowers that bare only pistills
pistillates
contains both pistil and stamen in the plant
monoecious
have two seperate flowers that contain the stamen and pistil
dioecious
flower clusters
Infloresences
can cut straight in half at any direction and will have symetry
radial symetry
can only be cut down the middle type of symetry
bilateral symetry
an ovary that is fully ripened
fruit
transfer of pollen from the anther to the stamen
pollination
occurs when sperm from pollen connects with egg cells of the ovule
fertilization
when an organizim can go through pollination by itself without outside help
self-pollination
pollination with outside organisms help
cross-polination
sweet liquid that attracts animals to flowers
nectar
allergic reaction to pollen
hay fever
any reproductive cell
gametes
reproduction through sperm and egg cells
sexual reproduction
transferes pollen from the stamen to the ovule
pollen tube
when it takes two sperm cells for an organism to reproduce
double fertilization
from one flower that has only one pistil
simple fruits
Simple fruits in which the entire ovary is fleshy
and juicy
berry
2 types of berrys
tomatoes, grapes, cucumbers, watermelons, and orange
fleshy and juicy, but not
throughout the entire fruit
Drupes
2 examples of drupes
Peaches, plums, cherries, olives, apricots, mangoes, and walnuts
Simple fruits with an outer fleshy layer and
an inner papery core
Pomes
2 examples of pomes
Apples and pears
simple fruits that consist of a
pod enclosing several seed
legumes
consist of
fleshy layers of ovary
small dry seeds with one or more wing-like structures attached to them
Samaras
2 examples of samaras
Maples, ashes, and elms
Simple dry fruits consisting of a seed enclosed in a hard covering, or shell,
nuts
2 types of nuts
chestnuts, hickory nuts, hazelnuts,
simple fruits consisting of a
seed and a shell
Achenes
fruits of the grass family
grains
2 examples of grain
barley, oats, rye, corn, and rice
include berries, drupes, and pomes
simple fleshy fruits
include legumes, samaras, nuts, grains, and achenes
Simple dry fruits
from one flower that has several pistils
aggregate fruits
2 examples of aggregate fruits
blackberries and raspberries
primary function of the fruit
to scatter seeds
an outside agent carries
the seeds
agent dispersal
scatter their seeds by bursting open when they are ripe and catapulting the seeds to a new
location
mechanical dispersal
the result of the process of flower and fruit formation
seeds
provides nutrition to the growing embryo
endosperm
protective covering of a seed
seed coat
3 parts of a seed
Seed coat,endosperm,embryo plant
tiny shoot that will develop into the stem and leaves of the plant;
plumule
3 parts of the embryo
plumule,radicle,and cotlyedons
sprouting of a seed
germination
period of inactivity, which helps prevent seeds from sprouting when conditions are unfavorable for the growth of young plants
Dormancy
Man that used peanuts and sweet poatatoes
George Washington Carver
